IMPROVEMENT IN WINDMILL-REGULATORS.

Specification forming part of Letters Patent No. 145,765, dated December23, 1873; application filed August 13, 1873.

the wind-wheel and vane. Fig. 2 is a sectional view, illustrating myimprovement for governing the mill. Fig.,3 is a top view of Fig. l.

Similar letters of reference indicate correspoutling parts in the threefigures.

This invention relates to an improvement for regulating Vautomaticallythat class of windmills the vaues of which are pivoted to the caps ofthe mill in 'such manner as to swing horizontally and change the facesof the windwheels, so that they will edge7 more or less to the wind,according to the force thereof. My object is to employ, in combinationwith a windmill of the description above named, and with the pumpthereof, a chamber which communicates with the interior of the pumpabove the `piston, and in which is a piston whose rod is connected witha gravitating-arm, to which the vane of the mill is attached, so thatthe surplus water, or that which cannot escape through the pump-nozzle,shall operate to regulate the speed of the mill, as will be hereinafterexplained.

The following'description of my invention will enable others skilled inthe art to understand it.

In the accompanying drawings, Arepresents the cap ofthe mill-tower,through which passes a hollow turning-center, B, the upper end of whichis flan ged and supported upon anti-friction balls h. On this center Bis formed a bearing, Gr, through the tubular portion of which passes theshaft of the wind-wheel E, on the inner end of which shaft is keyed acrank-wheel, e. To a wrist-pin on the crankwheel e is attached a rod, f,the lower end of which is connected to the upper end of a short groovedrod, C, by a pivot, g. The lower end of this grooved rod C has a ball,o, formed on it, which is received into a socket formed on the upper endof the pump-rod D, and through which a hole is made vertically. The rodl) passes down into a pump-stock, l), and has a piston or valve-bucket,t,4 secured to it, for raising water and forcing it out of cock ornozzle r. The pump rests on a platform, It, and alongside of it is avertical surplus-water cylinder, N, which communicates with the interiorof the pump above the piston tby means of a passage, y, as shown in Fig.2. The cylinder N is open at its bottom and closed at its top, exceptthe passage y, leading into the pump; and inside of this cylinder is apiston, m, the rod l of which rises through the cylinder, and hasconnected to it a rope or chain, k, which passes up, through the rod Oand turning-center, to and over a pulley, 1'., on bearing G, and isattached to an arm, W. This arm W is pivoted at j to the bearing G, andits outer end carries an adjustable weight, W. F represents the vaneofthe mill, which is pivoted at s, (see Fig. 3,) so as to swinghorizontally. tically-vibrating gravitating-arm V by means of a rod, p',which is pivoted at q p. Other means than those above described may beadopted for connecting the vane to the pistonrod l, although forsimplicity I prefer these means.

It will be seen from the above description that when the speed of themill is so great as to raise more water than can pass through the cock rthe surplus water will flow into the cylinder N above the piston m, andby the weight of this water and the force of the piston t the piston mwill descend, carrying with it the rod l and raising the loaded arm WVmore or less. The effect of this descent of the piston m is to changethe angle of the vane F with respect to the face of thc wind-wheel E andretard the speed of the mill. If the force of the wind is such as wouldbe lia-ble to break or derange the mill-works or the pump, then thepiston m will be forced so low as to move the vane around parallel tothe face of the wind-wheel, as indicated in dotted lines, Fig. 3, andthus throw the wind-wheel out of the wind.

By means of the cock r the discharge from the pump can be regulated orentirely shut, in which latter case the mill will stop.

It is obvious that my invention is applicable This vane is connected tothe verto double-acting pumps, :is Well as to the single-acting kind.

I am aware of the patent of Waiter S. Peck, granted June 19,1860, whichshows an atmospheric governor, consisting of an air-pump withregulating-cock, for controlling the vaines of a Wind-Wheel, andtherefore I do not claim, broadly, a pump for controlling the venes of2L Wind-Wheel; but

H :win g described my invention, what I claim es new, and desire tosecure by Letters Patent, 1s-

A surplus-Water cylinder, N, communicating with che interior of a pump,and having a piston Working in it which is connected to a vaneWorkingmeohanism, substantially as described.
